About these resources

Every guide here is written by Helen Hall, AAA Certified Member and former Vice President at Christie's, where she was responsible for entertainment memorabilia at the international auction level for a decade. The standards covered are the ones DIG Appraisals operates to. The case law referenced is the case law that governs every Form 706 and Form 8283 we sign.

If you are administering an estate, structuring a donation, or insuring a collection, these are the questions worth answering before the engagement starts. If you have a specific situation that isn't covered here, ask.
